3 Claims. (Cl. 50-238) This invention relates to siding and rooingmaterials andpertains particularly to building boards covered with metalor other sheet material.

One object of the present invention Iis to provide new and improvedbuilding boards covered with metal or the like and having anges or lips,made o f the covering material, and arranged along edges of the board toclose the joints between adjacent boards against the entry of wind, rainand the like.

A further object is to provide a new and improved covered building boardof the foregoing character which is wellradapted for use as permanentsiding or roofing.

Another object is to provide such new and improved covered boards inwhich at least some of the lips interlock with grooves formed in edgesof the boards.

Another object is to provide the overlapping lower edge of the buildingboard with a concealed and interlocked holding device in the upper partof the underlying board.

Another object is to permit concealed nailing of the underlying boardand holding the lower part of the overlying board in place with aconcealed and interlocked holding device.

Still another object is to provide such new and improved coveredbuilding boards which are low in cost and extremely easy to apply.

Further objects and advantages of the present invention will appear fromthe following description, taken with the accompanying drawings, inwhich:

Fig. l is a front elevational view of a covered building board to bedescribed as an illustrative embodiment of the present invention.

Fig. 2 is a vertical section, taken generally along a line 2-2 in Fig.1.

Fig. 3 is a horizontal section, taken generally along a line 3-3 in Fig.l.

Fig. 4 is a fragmentary horizontal section, somewhat similar to Fig. 3,but showing a vertical joint between two adjacent boards.

Fig. 5 is a fragmentary vertical section somewhat similar to Fig. 2, butshowing a horizontal joint between two adjacent boards. y

Fig. 6 is a view similar to Fig. 5, but showing Ia modied construction.

As already indicated, Figs. 1-5 illustrate a siding or roofing board 10which comprises a relatively thick sheet of building board 12 having itsfront surface substantially covered with a relatively thin coveringsheet 14. Preferably, the sheet 14 is made of metal, but it may be madeof plastics or other suitable materials. When made of metal, the sheet14 is preferably made of a metal which is corrosion-resistant, such asaluminum, for example. For the sake of appearance, it is preferred thatthe metal cover sheet 14 be suitably coated, as with baked enamel, orthe like.

A wide variety of materials may be employed for the building board 12which serves as the base of the siding or rooting material 10. Any ofthe common or suitable 2,961,804 Patented Nov. 29, 1960 building boardsmay be employed. Thus, it is merely by way of example that the board 12is illustrated as being made of insulating berboard, which may be coatedor impregnated with a waterproofing material, such as asphalt.

The base board 12 is illustrated as being generally rectangular inshape, for convenient application as siding or roofing. Thus, the board12 has upper and lower side edges 16 and 18, and left and right endedges 20 and 22. In this case, the side edges 16 and 18 are longer thanthe end edges 20 and 22 but, of course, this is a matter of convenience.

Along the upper and lower side edges 16 and 18, the board 12 hashalf-lap anges 24 and 26 which project upwardly and downwardly andextend for substantially the full length of the board. In this case,both half-lap flanges 24 and 26 are at the front of the board 12.Grooves or channels 28 and 30 are formed in the upper and lower sideedges 16 and 18, behind the half-lap flanges 24 and 26.

Along the end edges 20 and 22, the board 12 also has half-lap anges 32and 34. In this case, however, the half-lap flange 32 is at the rear ofthe board 12 while the flange 34 is at the front.

For a purpose to be described shortly, the end edges 20 and 22 areformed with rearwardly facing bevels or chamfers 36 and 38. The bevel 36is in front of the rear half-lap flange 32 and is formed as the frontwall of a V-shaped groove 40 in the left hand edge 20. It will be seenthat the right hand bevel 38 runs along the rear outer corner of thefront half-lap ilange 34.

From Fig. 5 it will be seen that the lower half-lap llange 26 on eachboard is adapted to overlap the upper half-lap ange 24 on the boardbelow, when the boards are applied as siding or rooting. This manner ofapplication slants the boards slightly, as seen in vertical section, soasrto promote the shedding of rain and moisture.

As indicated in Fig. 4, the front half-lap flange 34 on each board isadapted to overlap the rear ange 32 on the adjacent board, Thus, at thevertical joints, the boards are substantially flush with each other.

As shown in Fig. 2, the cover sheet 14 has rearwardly folded portions 42and 44 along the upper and lower edges 16 and 18. These portions 42 and44 are folded back around the half-lap llanges 24 and 26, to assist insecuring the cover sheet 14 to the board 12. It will be understood thatasphalt or other cement may be applied between the cover sheet 14 andthe front surface of the board 12 to make a firm, smooth bond.

The rearwardly folded portions 42 and 44 provide laterally projectinglips 46 and 48, which are adapted to be received in the grooves 28 or 30in the adjacent boards, as shown to best advantage in Fig. 5. Theinterlocking engagement between the lips 46 and'48 and the grooves 28and 30 seals out wind and moisture to a large extent, and helps to holdthe horizontal edges of adjacent boards together.

In the form shown in Figs. l-S, the lips 46 and 4S take the form ofdouble-folded portions of the cover sheet 14, extending Ylaterally asflanges which are tlush with the front of the cover sheet. Thus, eachdoublefolded lip 46 or 48 has a front portion 50 which is a continuationof the cover sheet 14, and a rear portion 52 which joins with therearwardly folded portion 42 or 44.

Along the end edges 2t) and 22, the cover sheet 14 is also formed withrearwardly folded portions 54 and 56. It will be seen that the left-handportion 54 is folded into the groove 40 along the chamfer 36, asindicated at 58. Similarly, the right-hand portion 56 is folded aroundthe chamfer 38 which extends along the right-hand ange 34, as indicatedat 60. This arrangement also assists in securing the cover sheet 14 tothe board 12.

From -Fig. 3, it will be-seen that the right-hand rearwardly foldedportion 56 is also formed with a lip `or flange 62, which is illustratedas being double-folded, in the manner of the lips 46 and 48. When theboards are applied as roofing or siding, the end lip 62 on each lboardis adapted to overlap the front of the adjacent board, as shown to bestadvan-tage in Fig. 4. The lip 62 will flex slightly, and will compressthe underlying portion of the adjacent board, so that the boards will besubstantially flush with each other along the vertical joints.

The underlying board is secured by concealed nails 66 which are driventhrough the upper half flange of the board; the nails are covered by thelower half flange of the overlying board. In addition to the concealedholding device of the lower part of the overlying board, a firm supportfor the overlapping 4board may be secured by furring strip 70 to be heldby nails 68, which also spaces the lower edge of the board outwardly bygiving the board a slight pitch.

As shown in Fig. 5, the upper lip 46 on each board is adapted to bereceived in the lower groove 30 in the board above. The lower lip 48forms an efcient drip edge, adapted to shed moisture.

Fig. 6 illustrates the construction of a modified board 72 which is thesame as the yboard 10, except that -the upper and lower lips 46 and 48are replaced with generally chisel-edged lips 74 and 76. These lips 74and 76 are formed by folding the cover sheet 14a rearwardly aroundchisel-shaped edge portions 78 and 80 on the half-lap flanges 24a and26a. The rearwardly folded portions of the cover sheet 14a aredesignated 42a and 44a. It will be seen that each chisel-shaped edgeportion 78 or 80 has a bevelled or angled outer end surface 82 whichfaces laterally and rearwardly.

The lip 74 at the upper edge of each board 72 is adapted to be engagedwith the groove 30 at the lower edge of the board above. The lower lip76 forms an efficient drip edge.

Thus, the illustrated boards effectively exclude rain and wind at `boththe horizontal and vertical joints, without any need for joint strips orthe like. The boards may be applied by simple nailing operations.

Accordingly, the boards provide low cost siding or roofing materialwhich is extremely easy to apply. The applied product is highlyserviceable and very attractive in appearance.

Various other modifications, alternative constructions and equivalentsmay be employed without departing from the true spirit and scope of theinvention, as exemplified in the foregoing description, and defined inthe following claims.
